I hear alot of this on this SVT forum about how Mach's & N/a Cobras cannot beat LS1's. But I can attest with you middlebrooks for I too have beaten a exhaust equipped LS1 with my 97 Cobra with just ignition, bumped timing, & a shifter. Irrevelant mods yet I pulled a car & some change on him. He told the story not me!
